Annular quenching furnace lining ------Ceramic fiber blanket

Ring quenching furnace is a continuous operation furnace. The fuel uses mixed gas. The normal furnace temperature is 1100 degrees Celsius.

Traditional ring quenching furnace lining insulation material: refractory bricks and heavy castables

1, High density, resulting in serious deformation of the furnace steel structure.

2. High thermal conductivity and lower insulation effect, waste energy and poor working environment

3, furnace lining is difficult to overcome the inherent internal wall expansion of the annular furnace, the external wall expansion defects

4, Low thermal sensitivity, to the ring furnace's computer operation to bring a certain negative impact, affect the product quality.

Ceramic fiber Feature:

1,low volume density , the weight of the ceramic fiber module lining is only 20% of the lightweight heat-resistant lining

2, low heat capacity, the heat capacity of the ceramic fiber material is 1/9 of the lightweight heat-resistant lining, which can reduce the lining heat storage loss.

3, Low thermal conductivity, ceramic fiber material heat transfer rate of 1/7 lightweight clay, lightweight heat-resistant lining 1/9, can greatly improve the lining insulation insulation effect,

4, Good heat sensitivity, better adapt to the heating furnace automation control.
